Digital pin
Upload the code to the board, and the on-board LED will light up every second.
// define led according to pin diagram
int led = 8;
void setup() {
// initialize digital pin led as an output
pinMode(led, OUTPUT);
}

}
Digital PWM
Upload the following code to see the on-board LED gradually dim.
int ledPin = 8; // LED connected to digital pin 10
void setup() {
// declaring LED pin as output
pinMode(ledPin, OUTPUT);
}
void loop() {
// fade in from min to max in increments of 5 points:
for (int fadeValue = 0 ; fadeValue <= 255; fadeValue += 5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
// fade out from max to min in increments of 5 points:

// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);

}
Analog pin
Connect the potentiometer to pin A5 and upload the following code to control the flashing interval of the LED by turning the potentiometer knob.
const int sensorPin = A5;
const int ledPin = 8;
void setup() {
pinMode(sensorPin, INPUT); // declare the sensorPin as an INPUT
pinMode(ledPin, OUTPUT); // declare the ledPin as an OUTPUT
}
